Microcontrollers Procurement Notes

Verify the specific suffix 'SO' corresponds to the SOIC-28 package configuration required for your design. Confirm that the '04' designation aligns with the 4 MHz operating speed specification. Ensure compatibility with existing UV-erasable EPROM programming infrastructure or equivalent factory programming services if code updates are anticipated.

Microcontrollers Selection Notes

Select this component when a cost-effective 8-bit solution with analog interface capabilities is needed. The 28-pin SOIC package suits space-constrained designs requiring multiple I/O lines. Consider the EPROM nature for applications needing code flexibility during development phases before transitioning to OTP or QTP variants for production.

Microcontrollers Part Context

This device belongs to the PIC16C64X series, which enhances the earlier PIC16C5X architecture. It shares pinouts and core functionality with the PIC16C641 but offers increased memory capacity. The series is designed for low-cost embedded control applications, balancing performance with power efficiency through fully static CMOS design.
